Application of Dye-Sensitized Solar Cell Technology in the Tropics: Effects of Air Mass on Device Performance
Abstract
Abstract - The performance of a Dye-Sensitized Solar Module (DSSM) of active area 175.12 cm2 has been investigated at a tropical climate area located 1.28˚S, 35.81˚E. Outdoor current density-voltage (J-V) characterizations were carried out at different AM values. The DSSM’s performance parameters; short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF) and solar-to-electricity conversion efficiency (η) were extracted from the J-V characteristics. The DSSM’s Voc reduced linearly by 2.05% from 8.31 V to 8.14 V as AM increased from 1 to 1.09. Jsc reduced linearly by 26.06% from 1.04 x 10-3 Acm-2 to 7.69 x 10-4 Acm-2 as AM increased from 1 to AM 1.09. FF increased linearly by 19.05% from 0.51 to 0.63 as AM increased from 1 at 1.09. η increased by 32.77% from 1.77% to 1.19% as AM increased from 1 to 1.09. The DSSM performed better during afternoon than morning hours. The results may be useful in tuning Dye-Sensitized Solar Cells (DSSCs) meant for use in the tropics. The design of Net Zero Energy (NZE) buildings in the tropics can also benefit from these findings.
